Answer:
It is given that p= 3.6, q=5.2
1. p - q= 3.6- 5.2= -1.6 [ As 5.2 > 3.6, and 3.6 is a positive rational number and 5.2 is negative rational number, So subtract 3.6 from 5.2 and apply negative sign before the result.]→When you subtract a number on the number line you move on left side of number line.
2. p + (-q)= 3.6 + (-5.2)=3.6 - 5.2= -1.6 [ +(-)= -, Reason same as above]→ move left of number line.
Drawn the number line below. In both the cases you get the same result and procedure are same , So number line A and B are same.
